The Persian Gulf

A collection of octocorals from the Persian Gulf is examined, and all species are identified to at least genus level. Sinularia erecta Tixier-Durivault, 1945; S. compressa Tixier-Durivault, 1945; Subergorgia suberosa (Pallas, 1766); Junceella juncea (Pallas, 1766); and Acanthogorgia spinosa Hiles, 1899, could be identified further. With some doubts Trimuricea reticulata (Thomson & Simpson, 1909), Menella cf. kanisa Grasshoff, 2000, and Verrucella cf. reticulata (Thomson & Simpson, 1909) are tentatively identified. Subergorgia perezi Stiasny, 1940 is synonymised with Subergorgia suberosa (Pallas, 1766), and Echinogorgia bahrelfarsi Stiasny, 1940 is assigned to Menella. Three new species are described and depicted.

During two sampling campaigns carried out in August 1998 and November 2002, 232 cumaeans from eight species belonging to the families Bodotriidae and Nannastacidae were collected. This paper presents the first ecological data on a shallow water tropical cumacean assemblage from the Persian Gulf, where 50% of the existing species were recently described as new for the science. Neither the environmental conditions (except for the sediment organic content) nor the cumacean assemblage descriptors differed between the two sampling periods. However, two different species dominated in each period (i.e. Eocuma travancoricum and Heterocuma inerme in 1998 and 2002, respectively) and the MDS analysis revealed differences in the assemblage composition between periods, particularly for the deepest sampling stations. An increasing density together with the increase in gravel content, and a decreasing density together with the increasing silt content characterized the distribution pattern of both the whole cumacean assemblages and the two dominant species, the latter being also positively correlated with the mean grain size and negatively correlated with depth and organic matter (E. travancoricum) and with depth (H. inerme).

Basinal Facies

AbstractFive areally distinct mineral assemblages are recognized in the Inferior Oolite of S. England. In each area, vertical (stratigraphic) variations are insignificant. The five assemblages comprise varying proportions of illite, illite-smectite, kaolinite, chlorite and kaolinite-smectite, the mixed-layer clays being largely poorly crystalline and randomly interstratified. A predominantly detrital rather than authigenic origin is suggested for most of the clays. Shallow-water platform carbonates contain kaolinite with illite and illite-smectite. Kaolinite decreases in abundance away from former mid-Jurassic land areas, the deeper shelf and more basinal facies being dominated by illite and/or illite-smectite. Possible volcanic contributions to clay suites are suggested but cannot yet be fully evaluated. The palaeogeographic usefulness of clay mineral suites is confirmed, even in carbonate-dominated systems.
